Dolphin DX5 Plus Power Cable Failure

Had my Dolphin DX5 failed to respond last week. Using your instructions, I was able to disassemble my pool cleaner to do a continuity check on power terminals inside the motor box to the power supply connector and found one of the wires was open circuited. Further disassembling the power cable feedthrough into the motor box, I found that water had leaked into the external power terminals seals and corroded one of the terminal connectors. Ordering Retrofit For Cable Conn.-3 Pin (9991279) for $11, I fixed the problem.
